Also, I learned recently that Or Meir gave a wonderfully accessible talk at Cambridge on a recent work of mine with Ben Rossman on chopping games (arxiv.org/abs/2609.01759), and brought together a few strands of top-down lower bounds.

A (non-convex) polygonal region (indicative of a strangely-shaped "art gallery"), vaguely triangular-shaped with big bumps at the corners, and smaller, long thin spiky bumps off of those. Three dots are placed, one near each corner of the triangle, colored red, green, and blue respectively. Dashed arrows from the dots to opposite walls indicate extremal lines of sight, and walls are colored corresponding to which dot can see them. Because of the bumps and spikes, which dot can see which wall is a complicated intermesh of the three colors.

A Simple and Efficient One-Shot Signature Scheme (Andrew Huang, Vinod Vaikuntanathan) ia.cr/2025/1906
Abstract. One-shot signatures (OSS) are a powerful and uniquely quantum cryptographic primitive which allows anyone, given common reference string, to come up with a public verification key pk and a secret signing state $\ket{\mathsf{sk}}$. With the secret signing state, one can produce the signature of any one message, but no more. In a recent breakthrough work, Shmueli and Zhandry (CRYPTO 2025) constructed one-shot signatures, either unconditionally in a classical oracle model or assuming post-quantum indistinguishability obfuscation and the hardness of Learning with Errors (LWE) in the plain model.

In this work, we address the inefficiency of the Shmueli-Zhandry construction which signs messages bit-by-bit, resulting in signing keys of Θ(λ⁴) qubits and signatures of size Θ(λ³) bits for polynomially long messages, where λ is the security parameter. We construct a new, simple, direct, and efficient one-shot signature scheme which can sign messages of any polynomial length using signing keys of Θ(λ²) qubits and signatures of size Θ(λ²) bits. We achieve corresponding savings in runtimes, in both the oracle model and the plain model. In addition, unlike the Shmueli-Zhandry construction, our scheme achieves perfect correctness.

Our scheme also achieves strong signature incompressibility, which implies a public-key quantum fire scheme with perfect correctness among other applications, correcting an error in a recent work of Çakan, Goyal and Shmueli (QCrypt 2025) and recovering their applications.

Weak Instances of the Inverse Matrix Code Equivalence Problem (Jesús-Javier Chi-Domínguez) ia.cr/2025/1909
Abstract. Nowadays, the Matrix Code Equivalence Problem shows potential applicability in constructing efficient and secure advanced digital signatures, focusing on linkable ring signatures, threshold signatures, and blind signatures. Current constructions of these advanced signatures rely on relaxed instantiations of the Matrix Code Equivalence Problem: given two pairs of equivalent matrix codes, find (if it exists) the secret isometry connecting the pairs. For example, the linkable ring signature construction by Chou et al. (AFRICACRYPT, 2023) builds on top of the Inverse Matrix Code Equivalence Problem: given three equivalent matrix codes, where one pair of the codes is connected by the secret isometry and another by the inverse of that isometry, find the secret isometry.

This paper studies the Inverse Matrix Code Equivalence Problem, focusing on the family of instances where the secret isometry is (skew) symmetric. Our main contribution corresponds to a new algorithm for solving these instances of the Inverse Matrix Code Equivalence Problem. As an implication, we identify weak instances of this kind of instantiation of the Inverse Matrix Code Equivalence Problem, for around 70% of the possible parameter set choices (i.e., code dimension k, and code lengths m and n), our algorithm runs (heuristically) in polynomial time. In addition, our results spotlight an additional 35% of parameter sets where the best algorithm for solving the Matrix Code Equivalence Problem, proposed by Couvreur and Levrat (Crypto, 2025), does not apply.

Our results have a crucial security impact on the recent blind signature construction proposed by Kuchta, LeGrow, and Persichetti (ePrint IACR, 2025), whose security is closely related to the hardness of solving these kinds of instances of the Inverse Matrix Code Equivalent Problem.

Unambiguous SNARGs for P from LWE with Applications to PPAD Hardness (Liyan Chen, Cody Freitag, Zhengzhong Jin, Daniel Wichs) ia.cr/2025/1913
Abstract. We construct the first unambiguous succinct non-interactive arguments (SNARGs) for P and incrementally verifiable computation (IVC) for P from the polynomial hardness of learning with errors (LWE). Unambiguity guarantees that it is computationally hard to find two distinct accepting proofs for the same statement.

As an application, we establish the first PPAD hardness result based on the polynomial hardness of LWE combined with a widely believed complexity assumption.

Central to our approach is a new notion of rate-1 witness-unambiguous batch arguments for NP, which we give the first construction from the polynomial hardness of LWE. This notion may be of independent interest.
